I needed a heater for 10 gallon tank and this has been perfect match. Price is right and so easy to install. No fuss adjusting temp either. My goldfish and Zebra snails like the warmer water! Absolutely No problems to date, but I know I can reach out at any time to customer service.
Great heater for my African Lungfish!

Do not trust the 1 star reviews. This heat works great for my Aquarium! It has never gotten to hot or to cold, never has burned my fish, and this heater has never stopped working, but i might have to turn it off in the summer because where I live, it gets 120 Degrees outside, and that could overheat my lungfish water.

I didn't realize that the heater is already set for around 76 degrees f, but my goldfish seem to like it because they keep swimming around it. every once in a while I do check my water to make sure it isn't too warm.
Better than aqueon equivalent.

The aqueon version of this same heater I had died after a little over a year of use. Hopefully this lasts longer than that. But tank is about 75°f for reference. Suction cup goes all the way around not clip on style like aqueon. Led lights to help determine the heater is working. Very nice so far!
Good little heater

Keeps my fish and snails nice and warm... I have a 2.5 gallon and a 3 gallon fish tank and this is perfect for them.

This heater was purchased for 2 of our 5 gallon tanks. It works ok in one but does not work at all in the other tank. It seems to be a hit and miss with this heater.

I was looking for advise on a heater for a 20 gallon fish tank. I went to the chat and asked what was good. I was advised that a 50 watt would do. so i ordered it and installed waited a few days before i put fish in and they died . Not impressed with service i received nor my fish
Do not buy!

I discovered my fish boiled to death today. The water was so unbelievably hot all my fish were white and dead. It’s December so there is no other reason why the water would be HOT except this heater malfunctioned. I feel terrible for those poor fish!
